To each their own on what they do and choice over another. I would just hope each was upfront with their teams / coaches on which takes priority so teams can make proper decisions when making offers to the girls. After all both soccer and lacrosse are team sports which players are committing to the teams and teammates. I personally am not a fan of people stating they are one sport in the Fall and another in the Spring then changing course at certain times that best suit their personal gains while possibly being detrimental other teammates. If you are upfront and honest on where your commitment stands then teams can expect when you will be out for games and either decide to live with it or make someone else the offer for that spot. I would not want my own decisions to harm another team where kids put so much time into being successful. After all even one loss could be the difference of girl getting to experience playoffs or not.
